Floating shelves look cool as they create the illusion that a shelf is floating. This illusion is due to the “absence” of any supporting system.
However, they are not without any support system. They are designed such that the support system is concealed. There are many ways to built and install floating shelves but everyone of the methods involved concealing the support system.
One form of supporting system are metal shelf brackets like those shown above. They are made of sturdy metal and have alloy steel coupling screws to ensure they are strong.
How they are installed are presented in the videos below. It the interior walls are using drywalls, then locating the studs of the drywall is a must for anchoring the metal supports. These metal shelf brackets can be installed in any other surfaces like concrete or brick walls.
We had curated instructional videos below. The first two videos are for installation in drywall while the third one is for concrete wall.
